Startingfresh:
Could it be that your son had a relapse and now is trying to right himself again? I do think that the unkempt appearance is a dead ringer - to me anyway.
I can imagine how upsetting it is after thinking he was beyond all of that. I would have felt that way too because a year of stability is a long time!
I am not sure what drugs he has used in the past, you only speak about marijuana in your signature. Many people can smoke that and function well - not my son but many can.
I'm so sorry you are worried. I just don't know what to say. I think you'll have to try to let him sort it out and see what happens. Agree that he can do it again as Earth says.
You just don't know what brought this all on if he won't talk to you about it.
Tough stuff.
